Leners Patent N 99,551, een February s, 1ero.

IMPRQVBMENT nl PRINTING'PRSBEB'.

ne `schedule referred to in :nm Lenen Pawn ssa are saure.

To all whom it may concern:

Be it known that I, Mnnnl'r'r GALLY, of Rochester, in the county ofMonroe, and State of New York, have invented a new and improvedPrinting-Press, called The Eclipse and I do hereby declare-that d "thefollowing is afull and exact description thereof,

, sition for making the impression, also the inclined ways E and F, andwheels or guides C and D, detached from other parts, and enlarged.

Figure 4 is a side elevation, showing like parts with those of tig. 3,with plate A in position of rest.

Figure' is a modification ofiparts ning. 'L l The first part ofmy'invention consists in the construction and use of inclined ways,which, in counection with Vwheels,rollers, or guides, shall govern 'andgive direction to the-movement of a plate, iu such a manner, that anextended reciprocating movement' may be secured tothe face of saidplate, by a much shorter movement of the part or parts which give motionto the plate without a corresponding disadvantage in leverage.

The second part of myinventionconsists in such a construction oi'anink-fountain for printing-ink, as shall secure a. constant and even flowor conduct of ink from the fountain to the distributing-apparatus, whensuch ink is too short, or lard-like, to be taken up by thefountain-rollerv of fountains in common use.

The third part of my improvement consists in' an improved constructionof a roller-carriage, on which a and therefore sensitive spring is usedfor giving elasticity to the movement ofthe inking-rollers, withoutnecessitating any projection whatever of springs beyond the body oftherollercarriage.

The fourth part of my invention consistsiu so con-v structing,arranging, and connectingthe wedges used for changing' the force ofimpression ou both sides of `the press, as to secure an almost instantand accurato. change by a single adjustment, and, attire same time,allow the use of the same device for throwing oli the impression atwill.

I will now describe more fully tue several parts of my invention,together with their operation.

The plate rollers, or guides' C and I), which move in or upon inclinedways E andF, inclined in opposite directions.

It will be seen, that the movement of wheel or guide D, down the inclineF, will cause ythe movement of A, figs. 1 and 3,' is furnished withwheels,

wheel or guide C `up the opposite incline E, which will bring'plate A tothe position shown in iig. 4.

It will also be seen,that if the wheels or guides C and .D are soarranged, as to bring the centre of gmv ity of plate A 'andcollarAcombined, midway between said wheels or gides, plate Av will be`perfectly bnlauced atevery point in its movement, so long as the ways Eand-F are equally inclined in respect to a horizontal line. y

1t will also be seen, that very slight power applied to plate or coliar,will produce the movement described.

A return movement of plate A. will be caused by the descent of guide Odown the incline E, which will bring guide D. toits former position.

The guards N'Fand' N" may be used, makingthe ways E and F in form of agroove or slot, cir-the guards l may be left olf.

The short parallel ways c* and aF allow a direct movemeunplnte A, formaking the impression.

It wilt be'seen sti'd furiiieryoy reference to iig. 1, thattiieextensive reciprocating movement oi' plate A will becaused by si shortlateintmovement oi' the connection-,rods or drawbarsGr", nnd, vastheguides C and D, which aneconstantly at eqn'ipoise, form the fnlcra forleverage, the difference in the extent of movement of plate A anddraw-barG will not cause a.` corresponding disadvantage in leverage.

The construction of ink-fountains has been such heretofore, as topreclude the .use af-certain kinds of printing-inks, which are tooshort, orv-lard-lke, to be taken up by the fountain-roller, or beconducted even by a well-fountain. I therefore make apressure-fouutuin,by which a lgreuluated pressure upon the ink shall keep it iu contactwith the fountain-roller, and also so construct the fountain, as toprevent ilooding of the roller, thus insuring a perfect conduct. Theinkfountainv is shown in fig. 1'. g

The tank Z is entirely enclosed, except a small aperture for contact ofthe ink with the fountain-roller. This aperture heilig small, onlyallowing 'contact of a line ofink, prevents the f oodiug of the rollerwhen 'pressure .is applied to the ink. g Y

' The gauge Z limits the quantity of ink conducted.

Pressure, bythe use of graduated springs or weights, is applied tothefollower W, a weight, Y, and graduated lever'X being represented in thefigure for that purpose. This fountain will conduct, perfectly, inkwhich-heretofore has been applied only by hand. Rei'- erence, forexample, may he made to Mathers Sons best wood-cut ink.

The roler-carriage Q is represented in iig. 1. For this carriage, I useyoke shaped rods, with ,coiled springs, (as in my improvement, caseF,)`but diliering entirely in arrangement. Instead of making the yokesfast to the body ofthe carriage, projecting also in front of the same, Iplace the yokes and springs T on the iside of the carriage, and alloweach end of the yoke to move back and forth through a portion of thehodyof the carriage, the journal'-box,.for the roller, being made fast toone end of the yoke.' The journal-box 1t is left open on theupper side,and the journal is vheld lin place by the guard S. Theples'sure of thehand behind'the yoke and spring T,.wiil force the joumal-boxRfor'- ward,to such anv extent as to allow the removal of the 'rollerfwhen desired.

I am aware that wedges have been used heretofore for increasing ordiminishing the force of the impression of a prin other devices, such asset-screws or pins, straight wedges have been used on both sides of apress. But in such presses as require adjustment at both sides, twoadjustments have been necessary, which, if not pcrfcctl y equal andaccurate, have occasioned the frequentbinding or breaking ofvdraw-bars,the injury of types, orthe injurious strain o f other parts of thepress, besides the loss vof time occasioned by making the-twoadjustments.

-In the device, as shown in fig.

I 2, I use two wedges, N N, with equal inclines. These wedges I connectby a bar, O, and place the wedges between inclined bearing-faces Land M;said bearing-faces having alike incline, tomatch the faces of the wedgesN ,Nh By moving the wedges further. between their counterbearing faces,the impression will be increased, This ting-press, and, that inconnection .with

ing of a misplaced sheet.

Remarlcs.

The straight inclines E and F may be varied, to produce tendency of-plate A forward or backward, if desired, ror the ways may be curvedinstead of being straight. In the use of a very heavy plate, vanadditional 4supporting-wheel, Rz, may be used, without changing thee'ect ot' the device, as shown in iig. 5.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A reciprocating plate,

bar O, whichk movement and perfectly adj ust both incombin'ation withwheels, rollers, or guides, moving in or upon oppositely-incliued ways,substantially as herein set forth.

2. A pressure ink-fountain, for printing-inks, substantially as hereinset forth.

3. The combination of rods and springs T, journalboxes`R, and guards S,substantially as herein.
